What happened is that the disklabel editor had pre-allocated chunks
for each partition:
old / 0-1G 1G
swap 1G-5G 4G
/var 5G-11G 6G
old /tmp 11G-12G 1G
old /usr 12G-20G 8G
The problem is that when you recreated your new / partition it used
2GB from the old /tmp (1G) + old /usr (8G) partitions (which is the
largest continuous space available), which left only 7G available for
you to partition between your new 2G /tmp and 5G /usr partitions.
0-1G 1G <- space available
swap 1G-5G 4G
/var 5G-11G 6G
new / 11G-13G 2G
new /tmp 13G-15G 2G
new /usr 15G-20G 5G
To fix this, you need to delete all the partitions and start over.
